sumyas food from royal canin large breed puppy to royal canin boxer 26. . i graded the large breed puppy food and it scored a lot lower than i would have liked. it got C,. however the boxer formula got an A+. i also notice that some times sumya stools are soft, she sheds alot, and gets splotchy red bumps on her ears and bumps on her head. i am thinking it could be from too much corn and chicken meal in her food.i know on the bag it says for boxers 15 month plus but she is only 10 months. think it would be ok to switch? :-/
